Filter by:Geriatric patients (age ≥ 65 years) undergo surgery for hip fractures that develops due to osteoporosis and falls. Dialysis-dependent chronic kidney disease is associated with an increased risk of cardiovascular comorbidity. Elective or urgent surgical operations may be required for geriatric patients with end stage renal disease. These patients have severe comorbidities, fluid, electrolyte disturbances and drug metabolism abnormalities during the perioperative period. For this reasons a careful anesthesia plan should be planned and performed. Spinal anesthesia can be used for hip fracture surgery at geriatric patients with chronic renal failure. Anterograde femoral intramedullary nailing can be performed in supine position with a fracture table. Intraoperative sedation might be necessary for patients under regional anesthesia on traction table. Dexmedetomidine is an alpha 2 receptor agonist that is being used as an agent for its sedative and adjuvant analgesic effects. The aim of this study is to evaluate the effects of dexmedetomidine premedication on geriatric patients with end stage renal disease, who will be undergoing a surgical operation for hip fracture under spinal anesthesia with hyperbaric bupivacaine and BIS (Bispectral Index) guided sedation with intraoperative propofol infusion.
Kidney transplant recipients usually lose their graft by rejection or by immunosuppressive drugs toxicity. In kidney transplantation, calcineurin-inhibitors (including cyclosporine A) are widely used. Their renal toxicity could be divided between an acute toxicity (toxic arteriolopathy and toxic tubulopathy) and a chronic toxicity (hyaline arteriolopathy, interstitial fibrosis, tubular atrophy and glomerulosclerosis). Several animal models have shown the implication of the mineralocorticoid receptor (MR) activation in those toxic phenomenons. The use of a mineralocorticoid receptor antagonist is useful regarding to the renal function and kidney histological damages. Several antagonists are available in France but none is indicated in kidney transplantation. Eplerenone appears to be the most selective molecule of the mineralocorticoid receptor and to have less adverse anti-androgenic effects than others molecules. Its principal adverse events are hyperkalemia and orthostatic hypotension. Mineralocorticoid receptor antagonists, especially eplerenone, could be very useful in the prevention of the nephrotoxicity induced by calcineurin-inhibitors. Classically, eplerenone is contra-indicated in patients presenting with an impaired renal function, determined by a creatinine clearance under 50mL/min. Moreover, in France, a warning is especially notified for the association with cyclosporine A due to the fact that no study have been done in this context. The investigators study first the safety of the use of eplerenone in association with cyclosporine A in kidney transplant recipients. Then, if it is safe, the investigators will study its efficiency in a large randomized controlled trial.
The purpose of this study is to evaluate the safety, tolerability, and immunogenicity profile of romosozumab after a single 210 mg subcutaneous dose in healthy participants and patients with stage 4 renal impairment (RI) or stage 5 RI requiring hemodialysis.
This is a non-randomized, open label, dose-ranging study of Bendamustine and Rituximab (BR) in patients with previously untreated or relapsed/refractory Chronic Lymphocytic Leukemia (CLL) who have multiple comorbidities with or without renal insufficiency. These agents are FDA approved for this indication. However, full dose bendamustine is associated with significant hematologic toxicity and a high rate of infectious complications in "unfit" patients and patients with significantly impaired renal function. This study will attempt to optimize and define adequate and safe treatment protocols for these patients with comorbidities and/or renal dysfunction. The study will accrue two independent patient cohorts which will follow a standard Phase I design. Patients with CLL who have significant comorbidities with or without minor renal dysfunction (CrCL>40 mL/min) will be accrued onto Cohort 1 of the study. Patients with significant renal dysfunction (CrCL<40 mL/min) will be accrued onto Cohort 2. Once the maximum tolerated dose (MTD) is determined, two expansion cohorts will be enrolled. There will be a treatment period of up to six 28-day cycles. On C1D1 all qualifying patients will provide samples for biomarker analysis. Six patients without renal dysfunction and 6 to 9 patients with renal dysfunction will also provide samples for bendamustine PK analysis. Accrual of both patient cohorts will occur simultaneously and will take place at two centers: Norris Cotton Cancer Center (NCCC) and Dana-Farber Cancer Institute (DFCI). Coordination of accrual to the study cohorts will be centralized at NCCC by Dr. Alexey V. Danilov.
The primary purpose of this study is to obtain a preliminary pharmacokinetic profile of MK-7145 2 mg immediate release (IR) following single-dose administration in male participants with moderate renal insufficiency. In addition, the study will evaluate the pharmacodynamic effect of a single dose of MK-7145 2 mg IR on 24-hour net natriuresis in male participants with moderate renal insufficiency.
The purpose of this study is to characterize the single-dose pharmacokinetic (PK) parameters of ixazomib (MLN9708) in cancer participants with either normal renal function or severe renal impairment (RI), including participants with end-stage renal disease (ESRD).
The study includes two study parts in which blood is collected from the patients. Study part A (observational study, already received positive ethics committee vote; Our sign: 12-330): Use of blood samples gathered during routine blood withdrawal Study part B (interventional study in the sense of additional blood samples but without an investigational product): Optional, for further pharmacokinetic questions: blood withdrawal with a maximum of 20 ml ( ten tubes of 2 ml each) within a maximal study length of four weeks. The primary objective of this study is to gain an overview about drug concentrations in plasma and/or cerebrospinal fluid (CSF), in order to determine pharmacokinetics of drugs in patients. Any drug may be tested, however the initial focus is on antiinfective, antineoplastic, and antipsychotic drugs. Many published studies show that there is a profound lack of information on pharmacokinetics and interactions of many commonly used drugs in clinical routine, and that drug concentrations, if controlled by therapeutic drug monitoring, are not in the therapeutic range (provided that such ranges are known at all).
The primary objective of this study is to evaluate the effect of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) tablet on renal parameters at Week 24 in treatment-naive and treatment-experienced HIV-positive, adults with mild to moderate renal impairment.
The purpose of this study is to evaluate the effect of anemia correction and vitamin D supplementation in kidney transplant recipients.
This is a non-randomized, non-interventional pilot observational study designed to follow high-risk patients through their surgical and hospital stay. The investigators will collect 2 4ml vial's of blood (total of 8ml) prior to surgery to assess CV biomarkers - inflammatory, metabolic, hypercoagulable and platelet.
